Server enabled for mcast receipt. When the server is acting as a proxy sends a mcast packet out over a slave client type socket, it receives the mcast packet on the server socket (which could then be forward out of the client socket....). This change prevents the server socket from passing up the libcoap stack a mcast packet that it knows the client socket is sending.
